The invention belongs to the technical field of audio processing, and particularly relates to a water scene audio generation method based on end-to-end, which comprises the following steps of: 1, selecting various water scene videos, and preprocessing the water scene videos; Step 2, obtaining a generator model through training according to the preprocessed data; Step 3, preprocessing the silent video, loading the silent video to the trained generator model, and outputting an audio corresponding to the silent video; And step 4, generating an envelope according to the sequence of the audios, loading the envelope to the trained tone intensifier model, and outputting the audios with enhanced tone. According to the invention, automatic generation of end-to-end outdoor water scene sound can be realized, the problem that time and labor are wasted for scene dubbing is solved, and meanwhile, the water scene audio is generated by using the trained model, so that the generation speed and the synchronization degree can be improved, and the working efficiency is improved.
